KHR_debug: test ObjectLabel(), GetObjectLabel(), ObjectPtrLabel() and GetObjectPtrLabel()

v10: Clean up whitespace nits, fix up naming and concurrency in the
     tests list (changes by anholt).

V9: replace array index magic numbers with enums

V8: make sure all each object is available in the OpenGL
implementation before doing get/set tests
fix copy and paste mistake with framebuffer/renderbuffer tests

V7: be defensive when testing max label, use fprintf for errors,
code tidy ups, and added get/set tests for each object type

V6: fix spelling of generated in multiple places

V5: Removed unneeded assignment that was also out of bounds

V4: Removed failure test that will never be true

V3: changed indentation to tabs, use test label constants
and remove unused variable

V2: fixed whitespaces, broke tests into subtests,
added missing build dir, and tidied up fail messages
